adding a new entry to grub?


i installed fedora core 3 on a second harddrive in my box but when asked to install grub i chose not to cuz i already have grub on my computer from installing fc2. I want to know how i can edit grub to include the new installed distro and if there could be any complications cuz it is loading a OS on a different harddrive. Is there a way i can boot it up without grub until i add an entry? thanks.

i did some searching and found out that i need to edit the /boot/grub/menu.lst file to add fedora 3 to the list. The problem is i need to access fc3 cuz i don't know what info to put for the kernal and initrd lines of the menu.lst file. The only idea i have is mounting the install disc and looking around there to get the kernal versions and whatnot. If anyone has any info that could help me access it i'd really appreciate it.

I think what you have done is right, just mount the disk and see the version. I haven't use FC3 before so I don't know the version of the kernel.

well i can boot into commandline using the install disc by going into rescue mode to look around but im stilling having trouble finding it. It should be in /boot/ right? I can't seem to find the boot dir. I only specificed the root / partition at installation so it should have installed it in there cuz i didn't make a seperate partition for it. and what exactly do i need for the grub config file?

ttitle: Name of menu item to be displayed in grub - i understand that.
kernal: where the kernal is so i can boot - i understand that
initrid line - don't understand that line.

here is my /boot/grub/menu.lst:
